Features

■ Powerful Harvard-architecture processor

❐ M8C processor speeds up to 24 MHz

❐ Low power at high speed

❐ Operating voltage: 2.4 V to 5.25 V

❐ Operating voltages down to 1.0 V using on-chip switch mode

pump (SMP)

❐ Industrial temperature range: –40 °C to +85 °C

■ Advanced peripherals (PSoC

® blocks)

❐ Four analog Type E PSoC blocks provide:

• Two comparators with digital-to-analog converter (DAC)

references

• Single or dual 10-bit 28 channel analog-to-digital

converters (ADC)

❐ Four digital PSoC blocks provide:

• 8- to 32-bit timers, counters, and pulse width modulators

(PWMs)

• Cyclical redundancy check (CRC) and pseudo random

sequence (PRS) modules

• Full-duplex universal asynchronous receiver transmitter

(UART), serial peripheral interface (SPI) master or slave

• Connectable to all general purpose I/O (GPIO) pins

❐ Complex peripherals by combining blocks

■ Flexible on-chip memory

❐ 8 KB flash program storage 50,000 erase/write cycles

❐ 512 bytes static random access memory (SRAM) data

storage

❐ In-system serial programming (ISSP)

❐ Partial flash updates

❐ Flexible protection modes

❐ EEPROM emulation in flash

■ Complete development tools

❐ Free development software

(PSoC Designer™)

❐ Full-featured, in-circuit emulator (ICE) and programmer

❐ Full-speed emulation

❐ Complex breakpoint structure

❐ 128-KB trace memory

■ Precision, programmable clocking

❐ Internal ±2.5% 24- / 48-MHz main oscillator

❐ Internal oscillator for watchdog and sleep

■ Programmable pin configurations

❐ 25-mA sink, 10-mA source on all GPIOs

❐ Pull-up, pull-down, high Z, strong, or open-drain drive modes

on all GPIOs

❐ Up to eight analog inputs on GPIOs

❐ Configurable interrupt on all GPIOs

■ SmartSense™ Auto-Tuning user module:

❐ SmartSense Auto-Tuning is easy to use and provides robust

noise immunity.

❐ SmartSense tunes your CapSense system automatically at

power up and monitors the system in real time to maintain

optimum performance.

❐ SmartSense significantly reduces design cycle time by

eliminating the tuning process from prototype to mass

production.

❐ SmartSense allows maximum production flexibility by

compensating for variations caused by using multiple

manufacturing sites and vendors.

■ Versatile analog mux

❐ Common internal analog bus

❐ Simultaneous connection of I/O combinations

❐ Capacitive sensing application capability

■ Additional system resources

❐ I

2C master, slave, and multi-master to 400 kHz

❐ Watchdog and sleep timers

❐ User-configurable low-voltage detection (LVD)

❐ Integrated supervisory circuit

❐ On-chip precision voltage reference
